【摘要】 简要介绍了改善钢筋混凝土短柱抗震性能的若干措施。为进一步提高短柱的抗震性能,本文提出了内藏“斜向劲性核心束”矩形截面混凝土短柱,并进行了7根短柱的抗震性能试验研究,试验表明,内藏“斜向劲性核心束”矩形截面混凝土短柱比普通矩形截面短柱的抗震性能显著提高。更多还原

【Abstract】 Current measures to improve the seismic performance of RC short columns from different ways in the world are summarized.To better improve the seismic performance of the RC short column,the reinforced concrete short column of rectangle section with concealed bracings is introduced in this paper,and the experimental researches of the seismic performance of seven RC short columns are finished.The results of experimental study prove that the reinforced concrete short column of rectangle section with concealed bracings has better seismic performance than common short column.更多还原
